feat: show package names and file paths during indexing

- Enhanced state-manager.ts to accept full file path and package name parameters
- Added package name extraction logic to orchestrator.ts
- Updated status messages to display package names and file paths during indexing
- Improved user visibility into what is being indexed in multi-package workspaces

Fixes #6907
